Organic/polymer electroluminescent devices employing single-ion conductors

An electroluminescent device comprising:

• a substrate;
• a first electrode deposited on the substrate;
• an electron-injecting layer positioned on the first electrode, the electron-injecting layer comprising a polymeric compound and a movable cation, the polymeric compound having at least one block of [O—(CH2)x′]y′ units and at least one non-movable anionic moiety, wherein x′ is an integer equal to or greater than two, wherein y′ is an integer equal to or greater than one;
• an emissive layer comprising an organic electroluminescent material, positioned on the electron-injecting layer;
• a hole-injecting layer positioned on the emissive layer, the hole-injecting layer comprising a polymeric compound and a movable anion, the polymeric compound having at least one block of [O—(CH2)x]y units and at least one non-movable cationic moiety, wherein x is an integer equal to or greater than two, wherein y is an integer equal to or greater than one;
• and
• a second electrode deposited on the hole-injecting layer.
